FIELD: mechanical engineering, gas and refrigerating industries. ^ SUBSTANCE: proposed pump consists of housing, piston, suction and delivery pipelines. Device contains additionally second piston connected with first one by rod and two winches with cables secured from outer right-hand and left-hand sides of end faces of housing. Inner part of housing is conventionally divided into three working chambers in which suction and delivery or liquid or gas takes place under action of piston at lifting and tilting of housing and at lowering housing into initial position, i.e. in horizontal position, by means of winch cables from right-hand and left-hand sides of housing end faces. ^ EFFECT: increased efficiency, safety and service life. ^ 1 dwg |
